Re: Master/Slave High CPU Usage

[Lance Norskog]

Yes, the Solr commit operations always reloads the index. And it
always throws away the Solr caches: queryresult, document, filter
query.

If you do this, please post your results.

 I am trying apply the Solr spell check component functionality to
 our
 data.

 The configuration set up I needed to make for it by updating config.xml
 and
 schema.xml is done as follows..
 Please let me know if any errors in it.

  I am not getting any suggestions in suggestion tags of solr output xml.

 I indexed word "Crust" to the field textSpell that is enabled for spell
 check and then I searched for
 "Curst"

 The queries i tried were :

 http://localhost:8909/solr/spell?q=Curst&spellcheck=true&spellcheck.collate=true&spellcheck.build=true&spellcheck.q=true


 http://localhost:8909/solr/spell?q=Cruste&spellcheck=true&spellcheck.collate=true&spellcheck.build=true&spellcheck.q=true&spellcheck.dictionar

Re: How to Transmit and Append Indexes

[Renaud Delbru]

 Have you looked at Apache Nutch [1]. It is a distributed web crawl and 
search system, based on Lucene/Solr and Hadoop.

Hi, all,

I am working on a distributed searching system. Now I have one server only.
It has to crawl pages from the Web, generate indexes locally and respond
users' queries. I think this is too busy for it to work smoothly.

I plan to use two servers at at least. The jobs to crawl pages and generate
indexes are done by one of them. After that, the new available indexes
should be transmitted to anther one which is responsible for responding
users' queries. From users' point of view, this system must be fast.
However, I don't know how I can get the additional indexes which I can
transmit. After transmission, how to append them to the old indexes? Does
the appending block searching?

Thanks so much for your help!

Amazon like search function

[nicksnels]

Hi,

I'm looking for ideas on how to implement an Amazon.com like search
function. If for example you do a search on - optimization algorithm java.
Amazon first returns results that contain all of these keywords, then
followed by a list that contains both the words "optimization algorithm",
then a list with books that contain the words "algorithm java" and finally a
list with books that contain both the words "optimization java". 

At the moment I'm using the solrQueryParser defaultOperator="OR" option, but
this returns to many results. I have tried to switch to the "AND" option but
that option returns to few results. So I would like to present the results
like Amazon does, so the user has some more options to choose from.

Kind regards,

Nick

Re: Amazon like search function

[Erick Erickson]

Take a look at DisMax, particularly the mm parameter
(minimum should match). It's kinda confusing, but I
it might help...

See: http://wiki.apache.org/solr/DisMaxQParserPlugin

I believe 3.x as well as trunk also have "Extended Dismax"
or eDismax that provides some additional capabilities.

Phrase Search & Multiple Keywords with Double quotes

[Pawan Darira]

Hi

I want to do pharse searching with single/double quotes. Also there are
cases that those phrases include special characters like & etc.

What all i need to do while indexing such special characters & while
searching them. How to handle phrase search with quotes

Please suggest

Thanks,

RE: Phrase Search & Multiple Keywords with Double quotes

[sivaprasad]

You have to escape the special characters.Use the below method to escape
 
public static String escapeQueryChars(String s) {
   StringBuilder sb = new StringBuilder();
   for (int i = 0; i < s.length(); i++) {
 char c = s.charAt(i);
 // These characters are part of the query syntax and must be escaped
 if (c == '\\' || c == '+' || c == '-' || c == '!'  || c == '(' || c == ')' 
|| c == ':'
   || c == '^' || c == '[' || c == ']' || c == '\"' || c == '{' || c == '}' 
|| c == '~'
   || c == '*' || c == '?' || c == '|' || c == '&'  || c == ';'
   || Character.isWhitespace(c)) {
   sb.append('\\');
 }
 sb.append(c);
   }
   return sb.toString();
 }

Re: solr dynamic core creation

[samarth s]

Hi nizan,

I have the same requirement of creating cores on the fly. Was looking
for some API provided by http solr server. Currently working around by
writing my own shell script on the server (solr server :) ). Any
better leads on the same?

Thanks,
Samarth
